Thermador Increases Cooktop Reliability, Reduces Cost
With Loctite 5920 Formed-In-Place Gasket
Realizes equipment investment in less than one year
Loctite 5920 Formed-In-Place Gasket.
Using an Asymtek automated dispenser equipped with a high-pressure spool valve fed by a five-gallon pail pump,
Loctite 5920 is now dispensed in two continuous beads, one on top of the other, to obtain the required bead height
of 0.025 inches above the rim of the part.
Loctite 5920 is a room temperature-curing, formed-in-place gasketing compound. Its non-sag copper paste
adheres easily to metal, glass, natural and synthetic fibers, wood, ceramics, other silicone rubbers, and many
plastic substrates. Loctite 5920 is used to fill voids and irregularities in surfaces maintaining a positive seal in
applications up to 662°F (350°C).
Results:
Thermador has realized a total annual savings in excess of $20,000. In fact, with the material savings that resulted
from replacing the pre-cut gasket with Loctite 5920, Thermador was able to pay back its equipment investment
in less than one year.
Problem:
Thermador, a major manufacturer of high end gas ranges
and cooktops, was looking to replace its current pre-cut
gasketing system. Pre-cut, extruded foam gaskets were
being used to create a seal between porcelain-coated
burner plates and the glass or stainless steel cooktops.
These gaskets were designed to enhance cleanability by
preventing food or liquids spilled while cooking from seeping
under the burner, with cooking temperatures to 650°F.
Proper assembly was required.
In addition, the method of assembly was costly and time-
consuming. Assembly technicians applied rubber cement
to the pre-cut gaskets and manually put them in place on
the burner plates.
Solution:
Loctite 5920 is dispensed by an Asymtek high-pressure
spool valve onto a porcelain-coated burner plate.
